At the same time, internal emails sent this summer by senior sales employees in its Worldwide Field Operations - which works with customers to deploy its technology - reveal it's contending with some hurdles as it tries to tell clients a "comprehensive software story" and sell those products alongside its highly sought-after AI hardware.
The last week of October, NVIDIA became the first publicly traded company to surpass a market cap of $5 trillion. In July, the AI chipmaker became the first publicly traded company to hit a $4 trillion market cap in early July. That achievement came just one month after surpassing both Apple Inc. (NASDAQ:AAPL) and Microsoft Corp. (NASDAQ:MSFT) in market cap as members of the $3 trillion market cap club.

In late 2025, a series of multi-billion-dollar deals in the artificial intelligence sector is causing déjà vu among industry veterans. Money, computer chips, and cloud credits are rotating in a closed loop among a handful of companies: Nvidia, OpenAI, Microsoft, Oracle, AMD, CoreWeave, xAI, and a few others. This has fueled a trillion-dollar AI boom or bubble built on intertwined investments and contracts.
That achievement came just one month after surpassing both Apple Inc. (NASDAQ:AAPL) and Microsoft Corp. (NASDAQ:MSFT) in market cap as members of the $3 trillion market cap club. In September, the company announced plans to invest up to $100 billion in OpenAI. As a result, Evercore raised its price target on NVIDIA to $225 from $214 while keeping an "Outperform" rating, citing the OpenAI deal as the impetus, while Barclays raised its price target to $240 from $200, maintaining its "Overweight" rating.
Apple has become the third company to see its market capitalization top $4 trillion, underscoring its role as one of the leading publicly traded tech companies and making it the second-most valuable company in the world.

Apple was the first company to top $1 trillion, $2 trillion, and $3 trillion in market capitalization. But Nvidia beat it to the $4 trillion mark, on the back of surging investor interest in artificial intelligence. That company's staggering chip sales have boosted its stock more than 400% since October 2023.
